BCD to Decimal Decoders
General Description
These BCD-to-decimal decoders consist of eight inverters
and ten, four-input NAND gates. The inverters are connect-
ed in pairs to make BCD input data available for decoding
by the NAND gates. Full decoding of input logic ensures
that all outputs remain off for all invalid (10–15) input condi-
tions.
Features
Y
Diode clamped inputs
Y
Also for application as 4-line-to-16-line decoders; 3-line-
to-8-line decoders
Y
All outputs are high for invalid input conditions
Y
Typical power dissipation 140 mW
Y
Typical propagation delay 17 ns

Alternate Military/Aerospace device (5442A) is avail-
able. Contact a National Semiconductor Sales Office/
Distributor for specifications.
